Q: At my home, I have a Small Flow Treatment Facility (SFTF Septic Tank); I am required to monitor the residual chlorine discharged from my system on a monthly basis and submit the results to the PA Department of Environmental Protection.The limits I must maintain are 0.3 mg/L to 0.5 mg/L.Can you tell me whether the AQUACHEK TRUTEST READER Item 10AC1095 is the correct unit to use, or which one you would recommend?Thanks

A: Yes you could use this. It checks for chlorine, pH, and alkalinity levels.
